UNITED STATES PATENT Orr1ca--- EDWIN A. BABBAGE, OF OAMBRIA, WYOMING.

COKE-OVEN.

SPECIFICATION forming part of Letters Patent No. 660,480, dated October23, 1900.

Application filed March 21, 1900. '3eria1 No. 9,570. (No model.)

To all whom it may concern:

Be it known that I, EDWIN A. BABBAGE, a citizen of the United States,residing at 0ambria, in the county of Weston and State of \Vyoming, haveinvented certain new and useful Improvements in Coke-Ovens; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

The object of this invention is the saving of expense in time andlaborin the manufacture of coke, particularly when the coal from whichthe coke is derived is hard to fuse.

The primary purpose of the invention is to compactly arrange the ovensand to utilize a certain percentage of the waste or escaping heat as ameans for heating them.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had to the following descriptionand to the drawings hereto attached.

While the essential and characteristic features of the invention arenecessarily susceptible of modification, still the preferred embodimentof theinvention is illustrated in the accompanying drawings in whichFigure 1 is a top plan view of a section of a battery or double row ofcoke-ovens, show- The ovens are arranged in two rows 1 and 2,constituting a battery, and are disposed as close together as possiblein order to utilize the heat to the best possible advantage andeconomize space. The ovens of each row are in a straight line, and thoseof one row are located opposite the spaces between the ovens of theother row. Considered individually the ovens are of ordinaryconstruction and of the beehive type, their crowns being provided withthe usual opening 3, through which coal is supplied, and adapted to beclosed by a cap or cover. As shown most clearly in Fig. 1, the batteryof ovens is located between parallel walls 4. of brick or masonry, theintervening spaces between said walls and the ovens being filled withearth, so as to retain the heat and provide a substantial structure. Thecoke is withdrawn from the ovens through the side door 5, and theproducts of combustion find an outlet through a flue or passage 6,leading from the oven at a point diametrically opposite the door 5 andabout in line with the top thereof. This fl ne orpassage 6 communicateswith a vertical passage or stack 7, located about in line with theopenings 3 of the row ofovens opposite that from which the passages 6lead. This disposition of the stacks 7 enables them to clear the track8, upon which the car carrying the coal is adapted to run. compactnessof arrangement and economy of space likewise result from arranging thestacks 7 in line with the openings 3 and between adjacent ovens. Theheat radiated from the passages 6 and 7 serve in a measure to maintainthe battery of ovens at a high temperature, which results in a saving oftime and labor in the coking process. Pillars or columns 9 of brick ormasonry are disposed at each side of the inner ends of the passages 6and rise vertically and are bonded at their upper ends and bridge saidpassages and constitute supports for the rails of the track 8. Thesepillars 9 rise to a short distance above the crowns of the ovens,whereby the rails of the track 8 are sufficiently elevated for theunobstructed traffic of the car thereover in each direction. The pillarshave a staggered arrangement and are alternately disposed so as to formsupports for the rails at regular intervals.

The base portions of the ovens are placed as close together asconsistent for strength, and by reason of their beehive or dome-shapedformation their upper portions are spaced apart, and in the spacesformed between adjacent ovens of a row are locatedthe passages 6 and 7,the elevation thereof being such as to admit of said spaces beingoccupied thereby. When the ovens are started, the openings 3 in theircrowns are closed. Hence the smoke and gases, as well as the heat, areconfined and the unconsumed products of combustion are forced intocontact with the flame, which causes ignition of the gases and materialincrease of heat, which facilitates the fusing and coking of hard coal.The ascending gaseous heat and the like are deflected by reason of theclosed top and are compelled to descend to the passages 6 before findingan outlet. Hence the coke is produced in a less time and at less expensethan is possible by the ordinary construction of oven generally in useand is of better quality. Moreover, it is possible to obtain a higherpercentage of coke from a given quantity of coal than is possible byovens as generally constructed and operated.

Having thus described the invention, what is claimed as new is 1. Inabattery of coke-ovens, parallel rows of ovens having the ovens of onerow located opposite the spaces between the ovens of the adjacent rowand having smoke passages leading from the ovens of the respective rowsinto the spaces formed between adjacent ovens of the opposite row,substantially as set forth.

2. In combination, a row of coke-ovens having smoke-passages leadingtherefrom about horizontally in the same direction, thence vertically, asecond row of coke-ovens located opposite the spaces between thefirstmentioned row and having smoke-passages leading therefrom in anapproximately-horizontal position, thence vertically, the verticalpassages of one row of ovens coming 0pposite the spaces formed betweenadjacent ovens of the opposite row, substantially as specified.

3. A battery of coke-ovens, disposed in parallel rows having the ovensof one row opposite the spaces formed between the ovens of the otherrow, smoke-passages extending from the ovens of one row and located inthe 1 spaces formed between adjacent ovens of the other row, pillarslocatedat the sides of the passages and projecting above the crowns ofthe ovens, and rails supported upon the pillars, substantially asdescribed.

4. A battery of ovens, comprising parallel walls, two rows of ovensarranged between the walls with the ovens of one row opposite the spacesbetween the ovens of the other row, said ovens having door-openings leading through the aforesaid walls, smoke-passages leading from the rearwalls of the ovens at a point about opposite the door-openings and inline with the top portions thereof and communicating with verticalpassages or stacks located between adjacent ovens and in line with theopenings formed in the crowns thereof, pillars at the sides of thehorizontal portion of the passages and extending thereover and to apoint above the crowns of the ovens, and rails supported upon saidpillars, the spaces between the longitudinal Walls and the ovens beingfilled with earth or the like, substantially as and for the purposesetforth.

In testimony whereof I affix my signature in presence of two witnesses.
